在网上找了很多excel导出和导入示例，代码不是很简洁，很多出错，自己在excel方法和控制器改了下。
首先我们看下导出的HTML导出接着我们看下Index/excelExport 导出的PHP代码：$list = M("user")->field("id,username,password")->order("id DESC")->limit(50)->select(); exportExcel方法如下：
$title = array('ID', '用户名', '密码'); //设置要导出excel的表头
exportExcel($list, '素材火', $title);function exportExcel($data, $savefile = null, $title = null, $sheetname = 'sheet1') { 接着我们看下导入的表单：
import("Org.Util.PHPExcel");
//若没有指定文件名则为当前时间戳
if (is_null($savefile)) {
$savefile = time();
}
//若指字了excel表头，则把表单追加到正文内容前面去
if (is_array($title)) {
array_unshift($data, $title);
}
$objPHPExcel = new \PHPExcel();
//Excel内容
$head_num = count($data);
foreach ($data as $k => $v) {
$obj = $objPHPExcel->setActiveSheetIndex(0);
$row = $k + 1; //行
$nn = 0;
foreach ($v as $vv) {
$col = chr(65 + $nn); //列
$obj->setCellValue($col . $row, $vv); //列,行,值
$nn++;
}
}
//设置列头标题
for ($i = 0; $i
$alpha = chr(65 + $i);
$objPHPExcel->getActiveSheet()->getColumnDimension($alpha)->setAutoSize(true); //单元宽度自适应
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setName("Candara"); //设置字体
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setSize(12); //设置大小
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); //设置颜色
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); //水平居中
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); //垂直居中
$objPHPExcel->getActiveSheet()->getStyle($alpha . '1')->getFont()->setBold(true); //加粗
}
$objPHPExcel->getActiveSheet()->setTitle($sheetname); //题目
$objPHPExcel->setActiveSheetIndex(0); //设置当前的sheet
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="' . $savefile . '.xls"'); //文件名称
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); //Excel5 Excel2007
$objWriter->save('php://output');

$this->error($upload->getError());

$this->goods_import($filename, $exts);

//导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入

//获取表中的第一个工作表，如果要获取第二个，把0改为1，依次类推
$currentSheet = $PHPExcel->getSheet(0);
//获取总列数
$allColumn = $currentSheet->getHighestColumn();
//获取总行数
$allRow = $currentSheet->getHighestRow();
//循环获取表中的数据，$currentRow表示当前行，从哪行开始读取数据，索引值从0开始
for ($currentRow = 1; $currentRow
//从哪列开始，A表示第一列
for ($currentColumn = 'A'; $currentColumn
//数据坐标
$address = $currentColumn . $currentRow;
//读取到的数据，保存到数组$arr中
$data[$currentRow][$currentColumn] = $currentSheet->getCell($address)->getValue();
